Die Casting Process, Defects, Design

The metal, typically a non-ferrous alloy such as aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine. There are two main types of die casting machines - hot chaer machines (used for alloys with low melting temperatures, such as zinc) and cold chaer machines (used for alloys with high melting

Beam Loads - Support Force Calculator

2020-8-4 · For a beam in balance loaded with weights (or other load forces) the reactions forces - R - at the supports equals the load forces - F. The force balance can be expressed as. F 1 + F 2 + . + F n = R 1 + R 2 (1). where . F = force from load (N, lb f). R = force from support (N, lb f). In addition for a beam in balance the algebraic sum of moments equals zero.

Maglev - Wikipedia

2020-8-8 · Maglev (derived from magnetic levitation) is a system of train transportation that uses two sets of magnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction.Along certain "medium-range" routes (usually 320 to 640 km [200 to 400 mi]), maglev can compete favorably with high-speed rail and airplanes.
